The plunger rod 49, Which may be reciprocated in any Well known and proper manner, and constitutes means for reciprocating the'plunger, is hollow and a suction is applied therethrough from a suit able source, this suction reaches through the hollow plungerrod 4.() and the holes so that when the carrier platform returns to its normal position the strip of paper 3 re mains attached to the under side of the plunger being held there by the suction.
